A SOLVENT-SOLUBLE NON-GELLED INTERPOLYMER OF: (A) FROM 5-45% BE WEIGHT, BASED ON THE TOTAL WEIGHT OF UNSATURATED POLYMERIZABLE MATERIAL, OF AN AMIDE OF A MONOETHYLENICALLY UNSATURATED CARBOXYLIC ACID; (B) AT LEAST ONE OTHER POLYMERIZABLE ETHYLENICALLY UNSATURATED MATERIAL COPOLYMERIZABLE WITH SAID AMIDE; AND (C) FROM 3-50%, BASED ON THE TOTAL WEIGHT OF UNSATURATED POLYMERIZABLE MATERIAL, OF DRYING OIL ACID ESTER OF ETHYLENICALLY UNSATURATED HYDROXY-CONTAINING MONOMER COPOLYMERIZABLE WITH SAID AMIDE AND SAID OTHER POLYMERIZABLE ETHYLENICALLY UNSATURATED MATERIAL, SAID DRYING OIL ACID ESTERIFYING AT LEAST 50% OF THE HYDROXY GROUPS OF SAID HYDROXY-CONTAINING MONOMER, SAID COMPONENT (B) CONSTITUTING THE BALANCE OF SAID INTERPOLYMER, AT LEAST A PORTION OF THE AMIDO HYDROGEN ATOMS IN THE INTERPOLYMER BEING REPLACED BY THE STRUCTURE
